I thought they sounded very good - but there were two different "versions" at Can Jam - the final version will be somewhere in between these two versions. So what I heard isn't likely to be the final version.

The housing is covered in a very nice black leather; otherwise they look the HE-5LE. As such, they are very comfy.

I was worried when leather was first mentioned since I prefer cloth on pads, but then I saw the detailed picture above showing the leather on the housing and was pleasantly surprised. Very tasteful and a bit luxurious. A nice alternative to the plastic Sennheisers and the metal Beyers/Grados of recent debuts.
